Temporal and spatial expression patterns of genes encoding 1-aminocyclopropane-1-carboxylate (ACC) synthase (ACS1 and ACS2) and ACC oxidase (ACO), ACC concentration, and ethylene production in leaves and fruit of 'Valencia' orange (Citrus sinensis [L.] Osbeck) were examined in relation to differential abscission after treatment with 2-chloroethylphosphonic acid (ethephon) alone or in combinatio...

Daily variations in net gas exchange, chlorophyll a fluorescence and water relations of mature, sun-acclimated grapefruit (Citrus paradisi Macfady.) and orange (Citrus sinensis L. Osbeck) leaves were determined in tree canopies either shaded with 50% shade screens or left unshaded (sunlit). Mean daily maximum photosynthetic photon flux density (PPFD) under shade varied from 500 to 700 micromol ...

This study was carried out on fruit of local orange (Citrus sinensis L. Osbeck) grown at private orchard Diyala governorate / Iraq, to the effect dipped fruits for 10 min in (0, 1, 2, 3% citric acid, 5 and 10% ginger) quality during 65- 105-days cold storage 5+1 with 85- 90% RH. Dipping acid solution reduced fruit's weight loss decay. Ginger extract significantly reserved acidity, total sugar s...

Fruit ripening in citrus is not well-understood at the molecular level. Knowledge of the regulatory mechanism of citrus fruit ripening at the post-transcriptional level in particular is lacking. Here, we comparatively analyzed the miRNAs and their target genes in a spontaneous late-ripening mutant, "Fengwan" sweet orange (MT) (Citrus sinensis L. Osbeck), and its wild-type counterpart ("Fengjie ...

BACKGROUND Vector-borne plant disease management can be enhanced by deployment of antifeedants in addition to the use of broad-spectrum neurotoxic insecticides. The effects of pymetrozine on Asian citrus psyllid (ACP), Diaphorina citri Kuwayama, feeding behaviour, survival and transmission of Candidatus Liberibacter asiaticus (Las), the presumed causal pathogen of huanglongbing, were investigat...

The Cusco Region, due to its geographical and climatic peculiarities, is prone extreme events, such as the increase in average temperature, intense rainfall, agronomic meteorological droughts. Citrus fruits, like oranges, adapt different climates; however, growth, flowering phenology fruit set are affected by changes temperatures lack of rain; therefore, these abiotic factors detrimental citrus...

Fruit ripening is a complex, genetically programmed process that occurs in conjunction with the differentiation of chloroplasts into chromoplasts and involves changes to the organoleptic properties of the fruit. In this study, an integrative analysis of the transcriptome and proteome was performed to identify important regulators and pathways involved in fruit ripening in a spontaneous late-rip...

Among Citrus species, the sweet orange (Citrus sinensis (L.) Osbeck) is most important in terms of production volumes and cultivated areas. Oranges are particularly appreciated for organoleptic characteristics high nutraceutical value fruits (thanks especially to their content antioxidants). Recent advances citrus genetic genomic resources, such as release reference genomes several cultivars, h...
